respiratory system: obtains oxygen so the energy in the nutrients can be extracted.

circulatory system: transports nutrients from small intestine to the othet tissues.

nervous system: regulates and controls digestive functioning.

dezoksy [38]

Answer:

option c punctuated equilibrium

Explanation:

Punctuated equilibrium occurs in a process whereby evolutionary changes occurs in some organisms in a rapid burst of time rather the conceived gradual changes that occurs over a long period of time. this burst of time might be in about 500,000 years. It is assumed that the organism has maintained/lives in stasis for a long period without a need for change, but then, once the change takes place (most of the time, due to an environmental factor), the organism quickly adapts to its new environment with this new adaptation.

Muscle tone is ________. the condition of athletes after intensive training the ability of a muscle to efficiently cause skeleta

Sedbober [7]

Answer:

a state of sustained partial contraction

Explanation:

Simply said, muscle tone means that there is a sustained tension in a muscle wile in a determinate posture. The muscle tone enable us to mantaing our bodies in a posture fit for resting or for also working, like sitting, being stand up or in a couch or sleeping. The changes in the muscle tones make us able to move. So contractions will follow depending what activity we are engaged on, as a continous and passive partial contraction of muscles change following changes in direction.

Muscle tones have contractions that do not produce enough tension to move, buy they keep it tense and firm.

Thererefore the tension is balanced and resting muscle tone balances bones and joints.

See below :)

In physiology, medicine, and anatomy, muscle tone (residual muscle tension or tonus) is the continuous and passive partial contraction of the muscles, or the muscle's resistance to passive stretch during resting state. It helps to maintain posture and declines during REM sleep.
